I found a bunch of these amongst some DEC cables. These are not real Digital, but are they clones/homebrews? Are these a standard serial cable using a Molex (as pictured) for some sort of PDP-8 serial option? The wire order is blue-white-red-green-orange-black.
Yes, they could be anything - but I wanted to give them a chance before they get scrapped. Maybe someone would see the Molex with the sequence of colored wire and say "ohhh...that is sort of like a BC123 serial cable".
